Does imessage work overseas?

I'm going to India over the summer, and i was wondering if imessage will work. In India, i will have internet. I have an iPhone 4 3G.

I already have an iPod touch but want an iPhone, is it worth it?

For Christmas last year I got the iPod touch 5th generation, and I'm very happy with it, but now everyone is getting iPhones, so i was wondering if it was worth me getting one.

My contract runs out in July so I have to get a new phone then anyway, and an iPhone would probably on be 2 or 3 pounds a month more than an alternative smartphone.

I would just get a basic iPhone 4 8g version (possibly refurbished if that was cheaper), as not to waste my money, and I'm sure I would still use my iPod a lot as it has more memory and is a lot better for most things, except you can't text, call or use 3g on an iPod.

I know I shouldn't just get a phone to fit in but, being a teenager, I do feel left out not having an iPhone, and I'm sure other people do judge me for not having an iPhone.

I honestly don't even know if my parents would allow me to have an iPhone anyway, because I spent a lot of my money on my iPod recently, but if they did would it be worth it?

Thanks so much for taking the time to answer my question, and if I can I'd be happy to help you in return.

What iPhone is this and its jailbreak or no?

I have a used iphone 4 (I think) - but I'm not sure if its an iphone 4 or not
The back cover of it shows A 1332 and the model of it under "Settings" is MC608LL

Would anyone be able to confirm if this is an iphone 4 or not?

One last question: how do I know if iphone is unlocked by apple and not jailbreak?
Because it doesn't have those applications that jailbreak iphones has like Cydia etc

I can't install certain apps to my iphone?

Okay so when I try to install a certain app, I can't because the button you clock is faded. For example I wanted to install a free app, but the app had a faded free button, so when I click it, nothing happens. I tried restarting, logging in and out, resetting all apps, etc. Here is a picture of how it looks.

Why can't my iPhone 5 be recognized on my PC?

My PC is Windows XP. It used to be able to recognize my iPhone 5 but it suddenly doesn't now. Now I can't connect to my iTunes because it couldn't be connected to my PC in the first place. I was thinking the USB cable was the problem but I was still able to charge it in my PC. It just won't recognize it so I can't connect to my iTunes. I've tried plugging it to other USB ports and PCs but the same thing happens. I'm so frustrated 'cause I can't put songs and ringtones on my iPhone now.

Gray vertical lines on iPhone 4?

I dropped my iPhone 4 on the floor and when I picked it up about 15% of the screen is a bunch of vertical gray lines. When I take a screenshot of the screen the lines don't show at all and if there's enough pressure put on the screen the lines disappear, but it comes back right after. And sometimes the top of where the lines start blinks. What is wrong with it? Is it a hardware issue?
